JOHN W. JONES OF PHIL IP DE OATESBY, OF HEREFORD, MARYLAND.

Letters Patent No. 114,015. dated April 25,1871.

'IMPROVEMENT IN CAR-COUPLINGS.

The Schedule referred to in these Letters Patent and maxin part of the same;

To all whom it may concern:

Be it known that 1, JOHN W. Jones on PHILIP DE OATESBY, of. Hereford, in the county of Baltimore and State of Maryland, have invented a, new improved Railroad-Oar Coupling; and-l do hereby declare that the following is a. full, clear, and exact description thereof, reference being had to the accompany- ,ing druwing"making part of this specification, in

Which- Figure 1 is a perspective view of a draw-head and coupling-pin ja.ttztch ed.

Figure 2 is an end view of the same.

Figure 3 is a. side view of a coupling-pin adapted for high undljow cars.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to improvements on couplings for railroad cars, which are so constructed as to be automatic in their action when two cars are brought together, and also which will uncouple should ,atuy' ear oi'zt train leave the track.

The object ofmy invention is to provide a. coupling-bar with spring engaging shoulders, which will be compressed when the said her is thrust into a drawhend and then springjout behind" a coupling-pin and effects coupling, and which will also be compressed and allow an uncoupling should a our turn over, as will be hereinafter explained.

The following description will enable others'.-skilled;

in the art to understand my invention In the accompanying drzuvihg- A represents 2t drew-head, which presents a flaring mouth that is formed by the streight side a and the diverging side a.

Near this diverging side (6 o. coupling-pin, B, passes vertically through the draw-head, which pin may be made like the pins used incombinzttion with couplinglinks. In ull'ot'he'r respects the draw-head A may be constructed in the usual well-known manner. '0 represents at coupling-bur, which may be made straight, as in figs. 1 and 2, or which may be bent as at s, fig. 3, for high and low platforms.

The extremities of the bar 0 are rounded as etc 0, for insuring their ready entrance into the drew-heads, uud on opposite sides of this barengaging shoulders b b are applied, which are on the extremities of springs D D, and which freely enter openings into or through the bar 0.

The shoulders I) b stand at right auglesftothe length of ,their coupling-bar, and are held out as shown in figs. 1 and 2, ex pt when compressed, as will be now explained.

When the coupling-pin B is in place,as shown in fig. 1, and the coupling-bar O is thrust intotthe drawhead A, between the straight side a and the pin B, with a spring shoulder, b, next this pin, this shoulder will be pressed into the bar 0 far enough to allow it to puss behind the pin B,'when the shoulder will spring outnud effect acoupliug. Ordinarily, the shoulder b will prevent the withdrawal of bar C unless the pin B is removed; but should a our turn over, the

bar 0 will turn with it, compress the shoulder 12, and

leave the draw-heed, thus uncoupling automatically.

Thesprings D, to which the shouldersb are applied, are secured to the bur O in such manner that they present oblique or wedgiug surfaces to the couplingpius while elfectiug a coupling, thus allowin" the her to enter the drew-head freely.

It will be seen from the above description that I have-a. very simple coupling which is u self-coupling,

. end which is it self-uncoupling shoul a car leave the track.

Having described my invention,

What I claim as new, and desire to secure by Letters Patent, is V The combination of the'spring engaging shoulders I), on coupling-bur O, with the coupling-pin B, or an equivalent coupling-shoulder, on draw-head A, substantially as described.
